Grain growers in New South Wales are disappointed but not surprised that GrainCorp will shut about 60 silos across the state.

The announcement of a massive change in direction has prompted mixed responses across farming areas.

Some farmers say a number of grain receival sites were in need of an upgrade, but others who rely on smaller silos, which are slated for closure, are not happy with the result.

The Warren silo is one of more than 60 Graincorp sites that will close in western NSW, which grain grower John Simmonds says is a disappointment.

"If you've you're on the wrong side of Warren and have to go through Warren to Nevertire, it's a huge cost. And in a good harvest there are huge delays," he said.

"We would have thought that Warren could have been a super centre as well, a 50,000-tonne silo that has great infrastructure and you could run in and out very easily. It's really strange that they've made this decision."

In an initiative called 'Project Regeneration', GrainCorp has announced plans to spend $200 million over three years to improve its grain storage network.

Some of the smaller sites in the state's central-west, including Bogan Gate, Canowindra, Warren and Forbes will be closed down over the next two years.

John Unger farms north of Parkes and west of Peak Hill, and says that it will mean grain will have to be freighted further distances over longer periods.

"It's just one less option that we've got if there are different freight rates or different grades being taken at different silos," he said.

"Basically, it's going to mean if a particular silo isn't going to take a particular grade in one year, you may find that you'll have to travel a lot further to get rid of that particular grade.

"This will mean a longer time that the truck is away from the farm, so suddenly instead of having one or two trucks per header, you're going to be looking at possibly three if your trucker has further to go and have a longer turn around."

Mr Unger says that that this will mean higher costs for grain growers.

Riverina grain growers the hardest hit

Grain growers in the state's south-west will lose about 30 receival sites in the region, half of all small silo closures across NSW.

Some are worried the company's overhaul of its rail and grain handling network will put more pressure on country roads.
